Shower Tile Calculator

Shower wall tile = (back wall + both side walls) × the tiled height, and the floor is counted apart: a 5 × 3 ft shower tiled 8 ft high takes 10 boxes of wall tile and 2 of floor tile.

Common questions

How do I measure a shower for tile?

Measure the back wall and both side walls to the tiled height, and the floor. Add curbs, niche returns and any fourth wall as extra surfaces. Wall and floor tile are rounded to boxes separately because they are often different tiles.

Should I subtract the valve and shower head openings?

No. Small cutouts do not save whole tiles. Subtract only areas that stay untiled, such as a window.

Does this include waterproofing?

No. Tile and grout do not waterproof a shower. The membrane, drain and corner details come from the waterproofing system you choose, and its installation handbook.

How to plan the quantity

The main shape is an open-front shower: a back wall, two side walls and a floor. Add the curb faces, niche returns and any fourth-wall surfaces as separate rectangles.

Subtract the face of an untiled opening from wall area, then add the tiled returns inside it. Wall and floor boxes round separately because they often use different tile.

Tile and grout are not the waterproofing assembly. Keep the membrane, drain, corners, curb and penetration details together in the quote.

Before you order

This is an area-based purchase list. Mosaics, edge pieces and pattern cuts need the product layout.
Shower slope, drain connection and waterproofing design are outside this area calculation.

Have prices moved?

Ceramic floor and wall tile cost 0.5% more in August 2026 than a year earlier (Bureau of Labor Statistics producer price index, preliminary).
